QBW Series Power Modules

GE Energy and Digi-Key introduce DC-DC Converters

GE Critical Power offers the QBW series of surface mount and through-hole converters, which operate over an input voltage range of 36 VDC to 75 VDC. They provide remote On/Off, output voltage adjustment, remote sense, overvoltage/current protections and overtemperature protection. The QBW018A0B series provide up to 18 A output current in an industry standard quarter brick, which makes it an ideal choice for small space, high current and 12 V intermediate bus voltage applications. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 93% at 12 V full load. This leads to lower power dissipation such that for many applications a heat sink is not required.
